Definitions

  • the invention relates to a method for corrugating an embroidery base between two winding shafts arranged in parallel on a large embroidery machine according to the preamble of patent claim 1.
  • the invention further relates to a system for clamping the material for the embroidery base according to the preamble of patent claim 11.
  • the object of the invention is also a Embroidery machine gate according to the preamble of patent claim 16.
  • gate arrangements are from the EP 0 919 657 and the EP 0 690 164 B1 known in which the embroidery base is stretched or corrugated between a lower and an upper shaft and after embroidery a first embroiderable surface spanned between the shafts, the embroidery base is rolled up from one shaft to the other or is corrugated so that the embroidery floor unwound from the lower shaft adjacent to the area already embroidered comes to lie in the embroiderable area between the waves.
  • the embroidery base is advantageously corrugated several times from one wave to the other, thereby balancing and aligning the tension and alignment of the weft and warp threads. So that the embroidery base is evenly stretched across its entire width at the start of embroidery, it is fastened by hand on both sides to a side tensioning bar and then the side tensioning bars are stretched horizontally across the tensioning direction between the shafts, also horizontally in the warp direction, and finally through the waves, in a vertical direction Direction, ie retensioned in the weft direction.
  • the embroidery base In the case of embroidery machines with a gate, which allows the embroidery base to be shifted by winding the embroidered area onto the upper shaft and unwinding unembroidered embroidery base from the lower shaft, the embroidery base is then released from the side tensioning strips for a displacement of the embroidery base, then the displacement, i.e. the undulation to finally hang the embroidery base back into the side tension bars. It is hardly possible to adjust the lateral tension after the waves again according to the tension before the shift to manufacture. As a result, there are shifts in the embroidery pattern where the one embroidery stage ends and the subsequent embroidery stage begins, especially in the lateral areas of the embroidery base, which affect the quality of the entire embroidery.
  • the EP 0 919 657 B1 discloses a method for shifting, also called waves, one with two side tension bars laterally tensioned with the embroidery base that can be moved translationally in the gate on an embroidery machine gate with an upper and a lower winding shaft, in which method the embroidery base that is corrugated on the winding shafts is stretched flat between them and is shifted by waves from one winding shaft to the other relative to the creel, while it is suspended in spikes of the side tension bars, so that at least part of the embroidery base remains tensioned during the shift by the side tension bars that are translationally shiftable in the creel, so that after the shift in this part to have the same tension as before the shift.
  • the embroidery base is lifted from the thorns that engage in the embroidery base with a surface of a release device that runs obliquely to the embroidery base level, and is thereby detached from the side tension bars.
  • at least part of the embroidery base remains during the displacement through the side tension bars excited to have the same tension in this part after the displacement as before the displacement.
  • the area adjoining the transition between the stages expediently remains taut, so that the tension in the embroidery bottom remains constant during the transition and the transition therefore invisibly fits into the embroidery pattern. It is imperative that the embroidery base is detached from the side tension bars over a length corresponding to the displacement in order to be able to wind it on the winding shaft.
  • the part of the embroidery base that is not tensioned by the side tensioning strips is advantageously re-tensioned in accordance with the tension of the part that has remained tensioned on the side tensioning strips, for example by manually hanging the embroidery base into the mandrels of the side tensioning strips, taking into account the thread path of the vertical weft thread.
  • the embroidery base can be tensioned by hand or with a tensioning device activated by the displacement.
  • the embroidery base is held in place during the movement of the gate in the vertical direction, so that the embroidery base can stand still relative to the needles. This can be achieved with the fabric pressers, which fix the embroidery base relative to the needles.
  • the side tensioning strips are advantageously translationally movable in the gate, so that they also move when the laterally tensioned embroidery base is moved and at least a part of the embroidery base remains tensioned during and after the displacement.
  • the side tension bars are divided into segments, which can be detached individually from the embroidery base or can be connected to the embroidery base, so that they can be detached segment by segment from the embroidery base, so that the side tension bar does not come into conflict with the rolling shaft.
  • the segments of the side tensioning strip are expediently fastened to a chain.
  • the segments can be moved with one another in a non-linear movement, so that the segments detached from the embroidery base can be removed from the embroidery base.
  • the chain forms a closed loop around two deflection wheels so that the segments are guided in a circular path away from the edge of the embroidery base.
  • the embroidery machine creel has release devices in order to release the embroidery base from the side tension bars. As a result, loosening by hand can be avoided and at the same time only the area of the embroidery base is loosened from the side tension bars, which must necessarily be loosened before winding up.
  • the release devices are arranged stationary on the gate and the side tension bars are movable relative to the release devices, so that the stick base and the side tension bars are released from each other when the embroidery base is moved in the gate.
  • the side tension bars have a variety of spikes for hanging the embroidery base. With these spikes, the stick base is held reliably in the tried and tested manner.
  • the segment-like side tension bars are connected to the chain and are guided straight through the rollers of the chain in a guide rail on the embroidery bottom side. The guide ensures constant tension even when the side tensioning bar is moved. With this from the EP 0 919 657 In the known method, the chain with its segments which are suspended in the embroidery base is pulled along with the waves from the embroidery base.
  • EP 0 690 164 B1 suggested the mass transfer to control the embroidery field on the winding shafts so precisely that the fabric can be wound onto the winding shafts under controlled tensile force, with a controlled vertical movement of the embroidery frame taking place at the same time.
  • the embroidery base on the embroidery needles be scanned in a touching or contactless manner with the aid of an encoder which detects a displacement of the embroidery base in the vertical direction and feeds this signal as a correction signal to a control unit which controls the material drive of the winding shafts in such a way that compared to the embroidery needles, the embroidery base relatively no longer moves during vertical movement of the embroidery frame.
  • a control unit which controls the material drive of the winding shafts in such a way that compared to the embroidery needles, the embroidery base relatively no longer moves during vertical movement of the embroidery frame.
  • the object of the invention is therefore to provide a method for corrugating an embroidery base and an embroidery machine creel with which, on the one hand, the lateral tension during the displacement of the embroidery base within the embroidery machine gate of the embroidery base can be kept constant and, in particular, the transition area from one embroidery stage to the next remains invisible.
  • Another object of the invention is to provide a system for clamping a new unembroidered material for the embroidery floor on an embroidery machine gate after the embroidery base has been completely finished.
  • Another object of the invention is to provide an embroidery machine gate in which the material can be stretched continuously onto the embroidery machine gate during the undulation.
  • This object is achieved by a method for corrugating an embroidery base according to the features of patent claim 1.
  • the object is further achieved by a system for clamping the material in accordance with the features of patent claim 11 and by an embroidery machine gate in accordance with the features of patent claim 16.
  • the area adjacent to the transition between the embroidery stages is always kept taut and in addition there is a shift of the embroidery base in vertical direction, ie in the direction of transport of the embroidery base on the upper winding shaft without the use of feelers and without a complex regulation for driving the pincushion of the side tension rod and the winding shaft.
  • at least the two opposing needle cushions located at the level of the needles of the embroidery machine are clamped with respect to the frame of the embroidery machine.
  • the embroidery base By engaging several pincushions on each side of the embroidery base during the corrugation, the embroidery base can be held taut over a greater length in the vertical direction, so that there is also no inclination to the weft and warp threads, that is to say an inclined distortion. Clamping at least one of the pin cushions on each side of the embroidery area by means of clamping means which are attached to the embroidery machine frame ensures that the clamped embroidery floor area cannot move in the vertical direction. Embroidery needles inserted during the corrugation are not bent as a result and therefore cannot break. The continuation of the embroidery pattern takes place exactly in the tenths of a millimeter range on the Where the previous embroidery motif ended.
  • the means for holding the pincushion during the corrugation are fastened to the embroidery machine frame. This slightly increases the moving mass of the gate. It is also ensured that the tension on the embroidery base is not changed in the horizontal direction and, in particular, that the clamped embroidery area cannot be moved in the vertical direction.
  • a particularly advantageous embodiment of the invention enables the needling of the fabric onto the pincushion to be carried out without any manual intervention, that is to say completely automatically, that is to say without manual intervention, as soon as the edge of the fabric from the lower fabric shaft is removed Embroidery area is approaching.
  • the needling is done very precisely and extremely evenly.
  • the synchronous outward pushing of the edge areas of the fed fabric or embroidery base ensures that the warp threads of the fed fabric are inserted into the new embroidery area without lateral displacements.
  • the construction of the embroidery machine gate and the holding and clamping elements is simple and no drive is required to precisely hold the stretched area of the embroidery base with the last stitches before the start of the corrugation in order to resume embroidery of the stitch pattern after the corrugation can.
  • extremely low forces act on the held area of the embroidery base during the corrugation. Due to the arrangement of the holding and clamping elements and their drives on the machine frame, for the pincushions on the stenter, the mass of the gate is not increased by this.
  • the means for laterally tensioning or pushing the incoming fabric outwards are fastened to the struts of the gate and are therefore always exactly in line with the tensioning frame when the fabric is needled.
  • the tensioning frame of a large embroidery machine comprises two spaced, vertically extending frame parts 3 and 5, between which an upper winding shaft 7 and a lower winding shaft 9 are rotatably and drivably mounted.
